`IHPILRATUS FOR INHALATIONS Filed A'ug. 13, 1936 Patented Aug. 23, 1938 UNITED STATES PATENT ori-ice APPARATUS FOR INHALATINS Lon Paul Sn, Louveciennes, France f "l Application August 1s, 1936, serial No. 35,772 In France August 14,1935

3 claims. "(ol. 12s-195) This invention relates to an apparatusifor inhalations and concerns more particularly an apparatus of the kind in which the vapours from the medicinal products intended for the `treatment of the affections of the respiratory pas-v sages, may be inhaled either through the nose or through the mouth and breathed or expired directly into the outer air without getting mixed with the said vapours to be inhaled.

10 The apparatus according to the invention which is of the kind provided with a hood above the receptacle in which the medicinal vapours are produced is essentially characterized by the fact that the hood ends with a connection or nozzle intended to receive one of two hollow extension pipes of a buccomasal separating device formed with a chamber divided into two comu partments intended to receive the nose and the mouth of the patient respectively and adapted to be placed in communication with the outer air by the forementioned extensions.

The invention also comprises a dropper device intended to incorporate the medicinal product with the solvent fluid, so as to provide for an eflicient inhalation.

The invention is illustrated in the accompanying drawing showing by way of example an inhalation apparatus according to the invention, and in which:`

Fig. 1 is an elevation sectional view of the apparatus,

Fig. 2 is a sectional view according to Ill- II of Fig. 1,

Fig. 3 is a sectional view of the bucco-nasal separator according to IIIIII of Fig. 1.

Fig. 4 is a sectional view of a dropper device.

Fig. 5 is a plan view corresponding to that of Fig. 4.

Figs. 6 and 7 are views similar to those of Figs. l and 5 showing an alternative embodiment.

According to the embodiment shown in Figs. 1 to 3, the inhalation apparatus is, in the usual manner, provided with a bottom receptacle 2l, from. which emanate the vapours intended for the treatment of the whole or a part of the respiratory passages.

Receptacle 2l is covered by an upper part or hood chiefly made up of a truncated body 22 resting with its large base upon the circular edge of receptacle 2i and formed at its upper end with a cylindrical connection or nozzle 23.

The apparatus is completed by a bucco-nasal separator device of moulded material preferably formed with a chamber 24 divided by a partition 21 into two compartments 25 and 26 corwill t the nose and mouth perfectly. Partition 51` 2l is arranged in such a manner that when the patient has applied his face to the upperedge of' the separator therev is no communication between compartments Y25 and 26. i

,Each compartment 25 or 26 has its botton 10i opening into a cylindrical extension 28 or 29 intended for insertion in nozzle 23. The extensions end preferably in the form of a cup, their lateral wall being provided :with an .opening 38 and 3l communicating with the 'inside of hood 15 22 when the corresponding connection is inserted in nozzle 23.

In order to obtain the proportion of air required for the mixture suitable for inhalations, hollows 32 for the admission of air, may be made 20 in the edge of receptacle 2 l.

The bucco-nasal separator being mounted as shown in Fig. l it is apparent that the patient can inhale the medicinal vapours through the nose and breathe them out through the mouth directly to the atmosphere through cylindrical extension 22 and opening 3i.

When extensionv 29 is inserted in nozzle 23, the vapours are breathed in through the mouth and breathed out through the nose. The cups provided at the bottom of extensions 28 and 29 serve as collectors to receive the fluids that are secreted by the nose or mouth in the course of the treatment. 35

In order to obtain an efficient and uniform inhalation throughout the duration of the operation it is preferable that the medicinal product should be incorporated with the solvent fluid in a regular manner, for example, drop by drop. 40

In Figs. 4 to 7 are shown two forms of embodiment of a distributing device making it possible to attain this result.

In the example of Figs. 4 and 5, the device which is intended more particularly for use in 45 the above-described inhalation apparatus is formed by a metal blank pressed so as to have in its centre a cup 33 from which extend two tabs 34 and 35, the ends of which are bent down. The bottom of the cup is provided with 50 a hole or outlet 36.

When the device is mounted in position, with its tabs in the hollows 32 of recipient 2|, cup 33 is lled with the medicinal fluid which flows drop by drop into the solvent within the receptacle 55 through hole or outlet 36 opening out, preferably above the level of the said solvent.

In the case of Figs. 6 and '7, receptacle 37 provided at the bottom with an outlet 38 is integral with an element 39 in the shape of a cup forming a oat. The bottom of receptacle 31 is above the bottom of cup 39, in order that, when the whole is floating on the solvent fluid, the medicinal product contained in receptacle 31 may flow out drop by drop through hole or outlet 38. I'he walls which connect receptacle 31 to element 39 are provided with holes 40 intended to allow the passage of medicinal vapours.

It is obvious that the invention is in nowise limited to the embodiment which has been more especially described by way of example, but that it extends to all possible modications coming fairly within the scope of the appended claims.

I claim:

l. In an apparatus for inhalations, a bucco-l nasal separating device comprising a hollow body having a rim adapted to fit over the nose and mouth of the wearer, an air tight partition dividing said body into a mouth chamber and a nose chamber, and a hollow extension depending from each chamber, each extension having a closed lower end forming a receiver and having an opening through its side wall, whereby either chamber may selectively be used for inhalation, the opening through the wall of the extension of the other chamber discharging the products of respiration into the atmosphere.

2. In an apparatus for inhalations, a receptacle having a hood upwardly extending therefrom, said hood forming a vapor chamber with said receptacle and having a vapor outlet, said vapor chamber having inlets for admitting air thereto, and a bucco-nasal separating device comprising a hollow body having a rim adapted to t over the nose and mouth of the wearer, and an air tight partition dividing said body into a mouth chamber and a nose chamber, each of said chambers having an opening adapted to connect said chamber with said outlet, said opening permitting either inhalation or exhalation therethrough, whereby either chamber may selectively be used for inhalations from said receptacle, the opening through the other chamber discharging the products of respiration in the atmosphere.

3. In an apparatus for inhalations, a receptacle having a hood upwardly extending therefrom, said hood forming a vapor chamber with said receptacle and having a vapor outlet, said vapor chamber having inlets for admitting air thereto, and a bucco-nasal separating device comprising a hollow body having a rim adapted to t over the nose and mouth of the wearer, and air tight partition dividing said body into a mouth chamber and a nose chamber and a hollow extension from each chamber, each extension being adapted to register with and to be inserted through said outlet, each extension having a closed outer end forming a receiver and having an opening through its side wall, whereby either chamber may selectively be used for inhalations from said receptacle, the opening through the wall of the extension of the other chamber discharging the products of respiration into the atmosphere. y
